DASH and Media-over-QUIC Transport Face-Off: Performance Showdown at Low Latency
summary
A testbed of FFmpeg instances, mockpp, mock origin and relay and a mo-player plus cockpit UI compares LL‑DASH (CMAF + HTTP chunking) against Media‑over‑QUIC (MOQT) under a repeating bandwidth profile 20→2→14 Mbps. Results in an ACM/IBC evaluation and the mq.streaming.university demo show MOQT sustains higher quality at 1 second target latency while DASH stalls and hesitates to upshift; simply running DASH over HTTP/3 does not avoid head‑of‑line blocking without multistream-aware players.
